Those who associate [others with God] say, "If God had so willed we would not have worshipped anything besides Him, neither we nor our fathers, nor would we have forbidden anything without His sanction." So did those who went before them. The duty of the messengers is only to convey the message clearly. 35 And assuredly We have raised in every community an apostle saying: worship Allah and avoid the devil. Then of them were some whom Allah guided, and of them were some upon whom the straying was justified. Wherefore travel about on the earth, and look on what wise hath been the end of the disbelievers. 36 Even if you are eager to guide them, God does not surely guide those who have gone astray: They will have no one to help them. 37 They swear their strongest oaths by Allah, that Allah will not raise up those who die: Nay, but it is a promise (binding) on Him in truth: but most among mankind realise it not. 38 So that He might make manifest to them that about which they differ, and that those who disbelieve might know that they were liars. 39 When We want to bring something into existence, Our command is, "Exist," and it comes into existence. 40
